On the upcoming episode, Henry and K.Will were assigned as teachers for elementary-school students during the military base's community support project. Henry especially walked in with confidence as he was assigned to teach English, but he was left flustered when the students asked about his first love thanks to a passage about two people having similar names falling in love.

When asked by a student, "Have you ever dated a person who has a similar name?", Henry's face turned red. K.Will was no help either as he added, "Does that mean you have a special relationship with [Girl's Day's] Hyeri who has a similar name?"

Henry then talked about his first love from when he was in middle school, sharing, "I fell for her at first sight. Everything she did was pretty in my eyes. Especially when she smiled and laughed, her eyes were the most pretty."

Find out more about his first love this Sunday at 6:20 PM KST!
